When the children of Israel left slavery in Egypt, they were pursued by the chariots of Pharaoh. At the banks of the Red Sea, the Presence of God appeared as a cloudy pillar and stood between the Egyptians and the Hebrew people. The Bible says that: it was a cloud and darkness to the one, and it gave light by night to the other, so that the one did not come near the other all that night (Exodus 14:20). To His covenant people, God was a protecting light; to His enemy He was a thick darkness.
Jesus once asked His disciples, Who do men say that I, the Son of Man, am?
They replied that popular opinions ranged from Him being an old-time prophet or even the recently murdered John the Baptist.
Then Jesus asked, But who do you say that I am? To which the Apostle Peter answered, Thou art the Christ, the Son of the living God.
Jesus responded, Blessed are you, Simon, son of Jonah, for flesh and blood has not revealed this to you, but My Father who is in heaven (Matthew 16:13-17).
The pillar of cloud functioned differently depending on which side of it a man stood. In a similar way, Jesus seems to be many different things to many different people, but His true identity is discerned only by a revelation from Heaven; that revelation is found only in the pages of the Bible.
